Application January 3, 1940, Serial No. 312,234

(Cl. 2992 l) 2 Claims.

This invention relates to means for releasing and diffusing perfumedvapors or odors of floral or other fragrant character to the atmosphere.

It is an object of this invention to provide an article of the abovetype which is flexible and readily attached to and detached from variousheat emitting sources in a simple and expeditious manner.

Another object is to provide for this article, impregnated with thepleasant smelling substance, a coating which is substantially imperviousto the passage of odors at normal temperatures, but which permits thecontrolled escape of the odors when subjected to a mild heat, and againrestores the impervious condition upon the discontinuance of the heat.

These and further objects of the invention will be apparent from thefollowing description, when considered in connection with theaccompanying drawing, in which certain forms of the invention areillustrated. One of the forms is shown as being applied to varioussources of the heat.

Referring to the drawing,

Figure 1 illustrates a form of the improved article encircling anelectric light bulb and having its extremities twisted together;

Fig. 2 shows the same form of the article applied to the heater of anautomobile;

' Fig. 3 shows a form of the article similar to that illustrated in,Figs. 1 and 2 applied to a steam radiator at two points; and

Fig. 4 shows an enlarged view of another form of the article which isslightly modified from the form illustrated in previous figures.

In the drawing, the reference 5 designates a flexible element which isprovided with a core comprising a plurality of longitudinally extendingwires 6 having a covering of absorbent material I. This covering may bealso made from fiber or the like. The flexible element 5 may becord-like or of cylindrical formation and of any desired length anddiameter.

The absorbent or fibrous material is impregnated with a substance ofpleasant and fragrant character such as suitably prepared essential oilsor the like, and is then subjected to a proper drying process. The odorof the substance with which the absorbent or fibrous material is treatedmay be of the fragrance of the woods or garden, and the fragrance is ofsuch strength that it has lasting results for a number of days while thearticle is being subjected to actual use. After the absorbent or fibrousmaterial has been suitably treated and the applied fragrant substancehas dried, the assembly is dipped in a paraflin or wax-like substancewhich forms an outer coating or seal therefor. This outer coating orseal 8 is of such character and thickness that it is substantiallyimpervious, at normal temperatures, to the passage of the fragrant odorswith which the absorbent or fibrous material has been impregnated. Whenthe coating is subjected to a source of mild heat it softens slightlyand becomes somewhat porous, thus permitting the con-' ponents are shownas applied about the neck of a lamp bulb 9' and with the ends of thematerial twisted together. The improved device, as shown in Fig. 2, isapplied between the grill work of the heating elements of an automobileheater. In Fig. 3 the improved article, as shown, is applied to a steamradiatorat a point near the top of the radiator and also at a point nearthe valve. In this connection the improved device may be simply laidupon the radiator or bent about it at any desired point.

In Fig. 4 an adhesive strip H is shown as applied at the ends of theimproved article. These strips may be attached so that the improvedarrangement may be suspended in a vertical position from a riser or thelike, or may be attached in a horizontal position to any source of heat.

While there is shown and described herein certain forms of the inventionby way of illustration, it is to be understood that it is not limited orconfined to the precise details of construction herein described anddelineated, as modification and variation may be made within the scopeof the appended claims without departing from the spirit of theinvention.

What is claimed is:

l. The combination of an absorbent material, an essential oil scented toa desired odor for impregnating said material, a wax-like coatingsubstantially impervious to the passage of odors at normal temperaturesapplied to the absorbent material to retain the odors, but pervious tothe application of heat thereto and becoming again impervious upon thediscontinuance of heat.

2. The combination of a flexible cord-like material comprising a core oflongitudinally extending wires, a fibrous absorbent material coveringthe wires,a substance having odors of fragrant character impregnatingthe material, a coating substantially impervious to the passage of theodors at normal temperatures applied to the absorbent material to retainthe odors, but returning to its impervious condition upon thediscontinuance of heat.
